Application filed September 15, 1914. Serial No. 861,796.

To all whom t may concern: Be it knownlthat I, HARRY G. ALDRIDGE,

of Rochester, in the co'unty of Monroe and State of New York, have invented a new and useful Improvement in Closures for Milk Bottles or Jars, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to closures for milk jars and. similar receptacles, an object of the invention being to provide a closure which may be'readily opened to permit the milk to. bedischarged without removing the closure from the jar or bottle.

Another object of the invention is to provide a discharging closure for milk bottles made from a single piece of paper stock without the provision of any separate fastening devices. l

To these and other ends, the invention consists in certain parts and combinations of parts all of lwhich will be hereinafter described, the novel features being pointed out in the appended claims.

' In-thedrawings: Figure 1 shows a common milk jar in vertical section with the improved closure attached thereto in closed position, the closure also being shown in section; Fig. 2 is a showing the cover of the closure open; Fig. 3 shows the two disks of the closure before being folded one upon the other; Fig. 4 is a In this instance; `the 'closure embodies a plan view of a closure with the two disks folded one upon the other; and Fig. 5 shows the closure with the hinged portion ofthe upper disk raised.

Referring more particularly to the drawings, 1 indicates an ordinary milk jar or bottle which has its mouth provided with an internal groove-for receiving a closure.

I member or disk 2 provided with a discharge opening 3, Vthe latter preferably being .en tirely surrounded by the stock of the disk which maybe paper, paper board, or any other desired material. To provide a spout for the discharge opening, the latter may have one edge formed with a curved tongue 4 which is separated from the body portion of the disk 2 by a curved score line permitting the tongue to be bent easily to the position shown in Fig. 2 by the finger of the user, the tongue normally lying in the plane cf the disk 2.

In order to provide a cover for the discharge opening, a second disk may ,bo emview similar to Fig. 1`

ployed, which like the first-named disk is of circular form of substantially .the same diameter as said irst-nained disk, although in practice', I prefer to make this second disk of slightly smaller diameter than the first-` named disk, permitting the second Vdisk to be removed more readily from the groove in 'the neck of the jar than the first-named disk so that its function as a cover will notbe interfered with. This second disk is pref-i erably made in one piece with the rst-v named disk and to this end the peripheries of the disk are connected at 6 a short neck which readily permits one disk to be folded upon the other.v This second disk preferably embodies two Portions 7 and y8 separated by a member 8 to' swing relatively to the member 7 in order to cover and uncover the discharge opening 3. A lateral lifting projection l0 connected to the portion 8 by scoring 11 lies at one side of a central line through both of the disksv when the latter are in the same plane as shown in Fig. 3, this arrangement scoring?) which permits the being provided in orderl that additional stock will not be required for the formation of this projection but that the otherwise wasted stock may be utilized. f

A'closure according to this invention is simple to manufacture and easy to operate. The two disks are formed simultaneously in connected relation so that all assembling is unnecessary and fastening devices are dispensed with. The disks are readily folded into superposed relation and can be easily fitted into the mouth of a jar. The cover portion of the upper ldisk can" be easily moved to uncover the dispensing opening in the lower disk without disturbing the position of the lower disk within the neck of the jar, the movement lof the cover being facilitated by the integral tongue or projection which may loe grasped with ease by the user. The closure enables the milk bottle to be used for dispensing the milk therefrom while, at the same time, retaining the closure in the neck of the bottle.

What I claim as my invention and desire spout-fprmingfportion being separated from i the remaining portion of the disk by ascore' so that it may be bent outwardly from ythe plane ofthe disk.

v2.-y A closure for milk bottles comprising vtwo Circular disks formed from a single4 blank and folded one upon another, one of said disks being provided 'with'a discharge opening and the other of said vdisks closing v ing wider than the other portion.

-said opening and being provided with a 10 another to permit a portion of said disk to score extending from one edge thereof to swing to open and close the opening, said `scored disk being slightly smaller in diameter than the one with the opening and the swinging portion of the scored disk beand the other of said disks having a transverse score permitting a portion thereof to bend relatively to the other portion to act as va cover for the opening, the swinging portion of the scored disk being Wider Vthan the other portion. l

4; A closure for milk bottles comprisingv two circular disks formed from one piece of material and folded one upon the other, 3.o

at one side thereof, one'of said disks being provided with a discharge opening'and the other of said disks being provided with la transverse score at an angle to the fold and Aalso with a tongue to one side of a central line through the two disks before they are folded.
